Parametric EAF Focuser Holder for LX200 Classic. This is a no belt direct focuser. (I found the belt versions to slip and loose focus) Included stl's are for an LX200 Classic 10". To customize the design, use OpenScad. Required: * Replacement bolts for focuser washer: 6-32x11mm (3 required) * Hardware for coupler: Bolt: M2.5 x 7mm Nut: M2.5 (2 of each required) * ZWO EAF Focuser * Aluminum Coupler that comes with the focuser * Scotch Extremely Strong Mounting Tape * Rubbing Alcohol or Isopropanol/Isopropyl Alchohol Assembly: * Assemble printed coupler (insert nuts and bolts) * Place aluminium coupler (the largest one that came with the EAF Focuser) on the EAF Focuser * Put tape on bottom of holder, keep focuser washer area clear * Place OTA horizontal and tighten clutch (to prevent the mirror shifting under gravity to make it easier) * Remove the 3 bolts holding the focuser washer * Clean area around the washer with Rubbing Alcohol/Isopropanol and let dry * Insert printed coupler inside the holder cage in the correct orientation * Apply holder and bolt down with the replacement bolts. 3 bolts + tape hold it in place. Orient such the flange on the top plate points upwards. * Tighten coupler to focuser knob * Bolt EAF to holder with the 2 bolts that came with the EAF * Tighten aluminmum coupler to printed coupler If you have problems with the EAF stopping prematurely due to not enough torque, focuser may be too tight, remove the focuser, undo the 2 set screws on it, and turn the brass wash a small amount CCW and tighten up the screws and replace. My focuser has always been hard to turn since it came from the factory.
